| 摘 要： | 螟虫长距茧蜂是玉米螟幼虫的重要天敌,一年发生2—3代,以卵或低龄幼虫在寄主体内越冬。自然寄生率为30—40％,最高70％。该蜂为多胚生殖昆虫,主要寄生1—4龄玉米螟幼虫,以3龄寄生率为最高。一头玉米螟(3龄)可育蜂39.12头,一头雌蜂可寄生玉米螟11.7头,繁殖子代460.05头。试验证明:人工繁殖和释放可提高田间玉米螟寄生率。

| Abstract: | Macrocentrus linearis, an important larval parasitoid of O_. furnacalis, has 2-3 generations a year in Shandong Province. It overwinters inside the host larva as egg or early instar larva. The natural parasitization rate of O. furnacalis by this polyembryonic parasitoid was 30-40%, with a maximum of 70%. The parasitoid attacked the 1st to 4th instar larvae of the host, the 3rd instar larva is mostly preferred. In experiments of mass rearing M. linearis. one female adult could produce a total of 457.7 progenies, as one 3rd instar larva of O. furnacalis could produce 39.12 parasitoids, and one female parasitoid adult could oviposit on 11.7 host larvae. Field releases of M. linearis resulted in an increased parasitization rate of Asian corn borer. |
